Overview

EN 3470:2019 specifies requirements for Steel FE-PM1503 (X3CrNiMoAl13-8-2) intended for aerospace forgings. The standard covers material production, heat treatment, dimensional limits and mechanical properties for forgings with a or D ≤ 150 mm. Typical production routes include vacuum induction melting (VIM) and consumable electrode remelting (CE), with delivery conditions either solution treated or solution plus precipitation treated.

This standard is part of the EN aerospace metallic materials series and is intended to ensure consistent high-strength, high-performance steel forgings for critical aerospace applications.

Key Topics

• Material designation: Steel FE-PM1503 (X3CrNiMoAl13-8-2).
• Melting method: Vacuum induction melted and consumable electrode remelted (VIM + CE).
• Form and limits: Forgings (a or D ≤ 150 mm); forged from specified forging stock.
• Heat treatment: Solution treated (900 °C to 950 °C followed by cooling to Td ≤ 15 °C) and, where required, precipitation (age) treatment (typically 545 °C to 575 °C for ~4 h) to achieve the use condition.
• Mechanical strength: Specified tensile strength range Rm = 1 200 MPa to 1 400 MPa for the delivery/use conditions defined in the standard.
• Chemical composition: Defined compositional ranges appear in the standard (examples include Cr ≈ 12.25–13.25 %, Mo ≈ 2.00–2.50 %, Ni ≈ 7.50–8.50 %, Al ≈ 0.90–1.35 % and low carbon). Refer to EN 3470:2019 Table for exact limits.
• Testing & inspection: Test samples, piece selection, and inspection criteria are referenced to EN 2157-3 and related documents.

Applications

EN 3470:2019 is targeted at high-strength aerospace forgings where a combination of corrosion resistance, strength and fracture performance is required. Typical practical applications include:

• Structural and highly stressed forged components in aircraft and aero-engines.
• Parts that require controlled microstructure and robust mechanical properties after solution and aging treatments.

Benefits for manufacturers and purchasers:

• Ensures traceable production routes (VIM + CE) and consistent mechanical properties.
• Provides clear heat treatment and delivery-condition specifications to meet design requirements.
• Aligns batch qualification, inspection and test-piece rules with aerospace procurement practices.

Related Standards

• EN 2157-3 - Technical specification for pre-production and production forgings (tests and sampling).
• EN 3359 - Forging stock and softened condition for FE-PM1503 (a or D ≤ 300 mm).
• EN 4258 - General organization of aerospace metallic material standards.
• EN 4500-005 - Rules for drafting/presentation of steel material standards.
• EN 4700-002 - Grain size and related wrought product rules.

For procurement or engineering use, consult EN 3470:2019 directly and coordinate the qualification program between manufacturer and purchaser as required by the standard.
